SPECIFICATION forming part of Letters Pater-1t; No. 375,470, datedDecember 27, 1887.

Application tied May 14, resi.

To aZZ whom, t may concern.- Y

Be it known that I, WILLIS H. BELKNAP, a citizen of the United States,residing at New York, county and State of New York, have inventedcertain'new and useful Improvements in Parasols, of which the followingis a specification. Y

This invention relates to parasols in which the sticks are made of twoor more pieces tted to slide together telescopically, so as to occupybut little space when not in use, and has for its object to supply asimple and efficient locking device for retaining the parts of the stickin extended position.

The invention consists of a metal cap or sleeve secured to the end ofthe hollow handle and provided with a chamber larger in diam.- eter thanthe bore of the handle, with the upper end of the chamber formedtoconstitute an internal flange, leaving an opening in which the upperpart of the stick is free to slide. This upper part is provided with acatch, which springs into the chamber when the stick is drawn out, theupper edge of the catch by coming in contact with the internal liange ofthe chamber preventing the entire separation The lower edge of the catchis rounded to permit the parts of the stick to be closed up by pressingthem together, the spring of the catch being sufficiently stiff to holdit within the chamber when the parasol is open and to hold the parts inclosed position by frictional contact with the interior of the hollowhandle.

To prevent any rotary motion between the parts of the stick when theparasol is in open position, depressions are made in the sides of thechamber, thus forming internal projections therein between which thespring-catch lits; but to describe my invention more particularly, Iwill now refer to the accompanying drawings, in which- Figure l is asectional view of a parasol provided with :my improvements opened. Fig.2 is a similar view showing the parasol closed.

Fig. 3 is an enlarged view of a part of the telescopic stick. Fig. 4 isa longitudinal section of the same, and Fig. 5 is a transverse sectionof the same on the line m x.

The lower part of the stick or handle a is hollow, and in it is fittedto slide the upper` part ofthe stick I, which is represented as a SerialNo. 938,202. (No model.)

hollow metallicrod. The runner c,connected to the stretchers d, ts overthe piece e,which is secured to the upper end of the stick and providedwith the spring-catch f. This piece e is of the same diameter as thehandle a, and to it is hinged the piece g, to which the ribs 7i arepivoted. The object of the hinge between the pieces e and g is to permitthe ribs 7L and covering, when opened, to loe turned over, so as tooccupy an angular position in relation to the stick.

There is nothing essentially new in the parasol thus far described, myinvention consisting of an improved locking-connection between thehollow handle a and stick b, which I will now describe. Fitted in thestick b, near its t', of which is tlat or slightly nndercutand its loweredge rounded. On the upper end of the hollow handle a is firmly securedthe metal cap or sleeve j, having a chamber, 7c, with the top closed inso as to form an internal flange, leaving a central opening for thestick to slide freely therein. This chamber k has depressions Z formedin its sides, thus making a series of internal projections, betweenwhich the catch i springs when the stick is extended, as shown at Figs.4 and 5, and thereby prevents rotation between the handle and stick whenthe parasol is in open position, so that telescopic sticks provided withthis device are for all practical purposes as rigid as solid sticks.`

catch i, by coming in contact with the internal ange of the chamber,prevents the complete separation of the two parts as they are drawn out,and while the catch by the resiliency of its spring holds the two partsin open position, the rounded lower edge permits the catch t' to beforced out of the chamber 7c down the interior of the handle a upon theapplication of longitudinal pressure to both parts of the stick, andwhen the parasol is in closed position, as shown at Fig. 2, the catch iacts as a friction-brake to Ihold the handle up in the body of theparasol. In this position the runner c is over the handle c.

Having now described my invention, what I claim,and desire to secure byLetters Patent, 1s

l. The combination, with a hollow handle lower end, is the spring-catchi, the upper edge,

The dat or undercut upper edge, i', of the IOO and stiel: adapted toslide therein, of a metal cap or sleeve secured to the upper end of thehollow handle, and provided with a Chamber larger than the bore ofthebottoni handle, and having internal projections, and a eateh in thehandle arranged to spring into the chamber between the projections whenthe handle and stiel; are extended, substantially as set forth.

2. In combination, a hollow handle, a stick adapted to slide therein, ametal cap or sleeve secured to the end of the handle, provided with aehainber larger than the bore ofthe hollow handle havin g internalprojections and its upper edge formed to constitute an internal flangethrough which the stick slides, and 15 a spring-catch having its upperedge Hat or undercut to stop against the internal flange of the chamberand its lower edge rounded, substantially as set forth.

In testimony whereof` I have hereunto Set zo my hand, at New York,county and State of New York, this 12th day of May, 1887.
